Explanation
- Examiners expect a tabular or point-wise distinction for "differentiate" questions — this avoids writing lengthy paragraphs and earns both marks quickly.
- One mark is for correctly listing examples of each type; the second mark is for stating the key difference (renewable vs. non-renewable / polluting vs. eco-friendly).
- Avoid simply listing examples without stating how they differ — that would lose the second mark.
